Does he really mean it? What does "move on" really mean?

I was going out with this guy for nine months. We broke up well he left me for such a small thing. He yelled at me to "move on" and kept repeating it. Does he really mean it? I asked other people and they said different things. My friend said she tells her boyfriend that when they get in a fight but she doesn't mean it. My other friend said just move on. What do you guys think?
